JOHN C. EDWARDS, OF BROOKLINE, MASSACHUSETTS, ASSIGNOR TO DRAPER COMPANY, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE v SPINNING-SPINDLE;

SPECIFICATION forming' part 0f Letters Patent NO. 741,638, dated October 20, 1903. Applioatio filed June 29, 1903. vSerial Nn. 163.618. (No model.)

To @ZZ whom t may concern:

Beit known that I, JOHN C. EDWARDS, a citizen of the United States, and a resident of Brookline, county of Norfolk, State of Massachusetts, have invented an Improvement in' so arranged that the empty bobbin may be readily applied to the spindle and as readily removed therefrom or doed, while the bobbin is retained firmly and securely in place by such means so long as the spindle continues to rotate. centrifugal force due to rotation of the spindle in such manner that the bobbiu is externally engaged and firmly held in operativev position upon theV spindle by the bobbin-re' tainingmeans.

The novelfeatures of my invention will vbe fully described in the subjoined specification and particularly pointed out in the following claims.

Figure l is a side elevation of a rotatable or live spindle and spindle-base with one embodiment of my novel bobbin-retaining means 1 applied thereto, a bobbin being shown in op- Fig. 2 is a partial sectional, detail on the line 2 2, Fig. 3, showing more@ clearly the construction and modeof opera- Fig. 3'

erative position.

tion of the bobbin-retaining means. is a top or plan view of the bobbin-retaining means detached, and Fig. 4 is a perspective view of one of the clutching members.

The rotatable spindle A, of usual or well known construction, is herein shown as having a rigidly-attached whirl W, secured to or forming part of the lower end of a sleeve W', attached at its upper end to the spindle in a manner familiar to those skilled in the art,

the sleeve in practice extending down outside the top of the bolster-case B, the latterhaving an oil snout or reservoir B and a hinged To this end I have utilized thecover B2 therefor provided with a downliold or projection b to prevent accidental lifting of the spindle, all of well-known construction. In the present embodiment of my invention the bobbin-retaining means is shown as applicable to spindles of the type above referred to without any change in the structure thereof, whereby spindles now in use may readily and at small expense be fitted with my invention, though it will be manifest hereinafter thatnew spindles may be provided therewith with the same facility. Herein said retaining means is arranged to coperate with bobbins D of the type used in automatic fillingreplenishing looms, such as shown in United States Patent No. 529,940, the head D having annularprojections or rings d, Fig. 2, to be engaged by the holding-jaws kin theshuttle; but by varying the shape of the engaging faces of the clutching members they may be adapted for use with any desired form of bobbin.

Referring to Figs. -2 and 3, I have shown a carrier comprisinga ,hubor` collar o, adapted to lightly fit the whirl-sleeve W in the present embodiment of my invention and provided with aV plurality ofsymmetrically-arranged radial arms c, three being shown in Fig. 3, each arm having two upturned parallel ears c2 thereon between the collar 'and outer end of the arm. A bobbin-clutching member is mounted on each arm, each composed of an elongated upturned body chaving its inner face notched at c4 and outwardlybeveled at c5 at its upper end, the lower end of the body being turned outward and enlarged or thickeued, as at c6, to form a weighted extension .heavier than the body c3. (See Fig. 4.) The lower end of the body has a hole o7 to receive a fulcrum-pin o8, which is passed through and I firmly held in the upturned ears c2, the lower end of the body being inserted between them with the extension c6 extending outward beyond the ears and'substantiallybelow the fulcrum. A pin 20, Fig. l, may be driven through the collar c into the whirl-sleeve, if

desired, to absolutely and'rigidly confine the collar in place. When the spindle is at rest, the weight of the extensions oG will cause the bodies of the clutching members to swing outward away froxnthe center of the spindle; but when the latter is rotating at speed the IOC centrifugal force will operate to lift the extensions, and thereby move the bodies c3 inward on their f ulcra es. Manifestly the space between the inner faces of the said members will then be reduced, and the construction is such that then this space will be smaller than that occupied by a bobbin-head.

Vhen a bobbin is applied to the spindle, it is slipped down onto the whirl-sleeve, which it tits loosely and by which it is partly positioned, the head of the bobbin passing down between and spreading apart the clutching members against the centrifugal force by which they are controlled. As the bobbin is slipped down to position the notches c4 receive the rings don the bobbin-head, as shown clearly in Fig. 2, and the latter will be more tightly engaged and held the higher the speed of rotation of the spindle. Not only will the bobbin be rotated with the spindle, being firmly held by the clutching members, but the latter will also prevent any lifting of the bobbin during the operation of laying yarn thereupon.

The carrier is herein shown as forming a support for the bobbin to position it vertically, and by pushing a bobbin down to such support it will be manifest that the bobbin will always maintain a fixed vertical position with relation to the spindle.

The outwardly-beveled upper ends c5 of the bobbin-clutching members facilitate the entrance of the bobbin-head between them, as will be manifest.

The bobbin can be readily removed or doffed without stopping the spindle by grasping the bobbin firmly enough to overcome the grip of the clutching members and stop it and then lifting it off the spindle.

When the spindle is at rest, the extensions c( drop down upon the arms c' beyond the ears c2 and limit the outward movement of the clutching members on their'fulcra, and when the spindle is running empty the clutching members will move inward until the eX- tensions c, thrown upward by centrifugal force, attain a position. of equilibrium.

The rapid rotative movement of the clutching members might increase the resistance due to air-pressure to an undesirable extent, and to obviate such resistance I have shown a wind shield or guard Consisting of a thin, preferably metallic, plate S, bent into an annulus and secured to the arms c byinturned ears s. The annular guard surrounds the clutching members and effectually overcomes the wind-pressure or resistance referred to. It will be seen that the arms c' extend outward above and quite close to the whirl downhold bX and reservoir-cover B2, so that the latter cannot be tipped either to release the.

whirl or open the reservoir when the spindle is in motion.

When it is desired to release the whirl or open the reservoir, the spindle being at rest, it is turned until the opening S in the shield S is above the cover B2, said opening being located between two of the arms c', as shown in Fig. l.

My invention is not restricted to the precise construction and arrangement herein shown and described, for so far as I am aware it is broadly new to provide a rotatable spindle with centrifugallyacting bobbin -clutching means to engage the exterior of a bobbin, and

accordingly various changes or modifications may be made by those skilled in the art without departing from the spirit and scope of my invention.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination wit-h a rotatable spinning-spindle, of centrifugally-acting bobbinclutching members mounted to rotate therewith and free to move inwardly to engage the exterior of a bobbin and rotate the same with the spindle.

2. The combination with a rotatable spinning-spindle, of centrifugally-acting bobbinclutching members mounted to rotate therewith,and axially arranged with relation thereto, said bobbin clutching members being moved inward by or through rotation of the spindle to externally engage and hold a bobbin to rotate the same with the spindle.

3. The combination with a rotatable spinning-spindle, of upturned and axially-arranged centrifugally-actingbobbin-clutching members mounted to rotate with the spindle and free to move inwardly to externally engage and rotate a bobbin with the spindle.

4. The combination with a spinning-spindle, of a whirl-supporting sleeve secured thereto, a carrier mounted on the sleeve,and centrifugally-actiug bobbin-clutching means mounted on the'carrier and adapted to move inwardly to engage the exterior of and rotate a bobbin with the spindle.
